According to ABC News‘ 2016 election tracking poll, Clinton is leading Trump 50 to 38 percent, and the poll suggests that the difference is a result of Trump’s latest controversies regarding his treatment of women and his claims that the election is rigged.

On Monday, Trump suggested the polls are rigged, too. “Major story that the Dems are making up phony polls in order to suppress the the Trump. We are going to WIN!” Trump tweeted.

The ABC poll found that some of Trump’s most loyal women supporters have since moved away from the GOP nominee. The change comes as Trump finds himself denying accusations by multiple women that he sexually assaulted them years ago.

The allegations began pouring in after The Washington Post published a video of the presidential candidate making lewd comments about groping and trying to have sex with women during a 2005 conversation with Access Hollywood‘s Billy Bush that was caught on a hot microphone.

Although Trump’s tweets suggest he is not accepting his standing in the polls, his campaign manager, Kellyanne Conway, acknowledged the lag to NBC News on Sunday, saying, “We are behind.”

“She has some advantages, like $66 million in ad buys just in the month of September, thereby doubling her ad buys from August,” Conway said of Democratic nominee Hillary Clinton. “Now, most of those ads are negative against Donald Trump, classic politics, personal destruction…kind of ads. And that she has tremendous advantages.”

While Conway has attributed part of Clinton’s lead to her ads, CBS News reports that Trump has also increased his advertising budget, surpassing Clinton in TV ad buys for the first time after spending $14 million on advertisements in the third week of October.

Clinton is no stranger to controversy though. Her use of a private email server during her time as Secretary of State has long plagued her campaign. And a recent hack by WikiLeaks rolled out more than 12,000 internal emails illegally obtained from the private account.
